Abstract

PURPOSE: To present the first parallax-free exophthalmometer design.

BACKGROUND: Exophthalmometry is an important clinical tool. We provide a historic overview of clinical exophthalmometer designs, and we review current problems encountered in exophthalmometry.

METHODS: We present a new and parallax-free exophthalmometer design that we have evaluated in 49 patients visiting our orbital clinic.

RESULTS: The mean age of the patients was 49.8 years and 72% were female. The Pearson interobserver variation was 0.97, and 94% of the Hertel values measured by the two observers were within the limits (1.6 mm) of agreement.

CONCLUSION: This meter appears to be a reliable instrument for exophthalmometry. It is the first instrument that allows for a complete parallax-free measurement.
